摘要:

采用电催化氧化法对高浓度含酚废水进行处理,考察了pH值、温度、电压、NaCl的投加量等因素对酚去除率、COD去除率的影响.结果表明,这种方法能有效去除废水中的酚和COD,特别是电压、Na-Cl的投加量这两个因素对酚和COD的去除率影响较大.采用了两种复合电催化氧化法处理含酚废水,一种是直接投加H2O2,结果表明酚去除率可达95%以上;另一种是加浓H2SO4,在适宜条件下,酚去除率可达90%以上.由此得出,对含难降解有机物废水的处理,电催化氧化法能达到满意的效果.

Abstract:

The effects of pH, temperature, voltage, NaCl dosage and other factors on phenol removal rate and COD removal rate were investigated by electrocatalytic oxidation. The results show that this method can effectively remove phenol and COD from wastewater, especially the two factors of voltage and Na-Cl dosage have a great influence on the removal rate of phenol and COD. Two composite electrocatalytic oxidation methods were used to treat phenol-containing wastewater, one was direct addition of H2O2, and the results showed that the phenol removal rate could reach more than 95%. The other is concentrated H2SO4, and the phenol removal rate can reach more than 90% under suitable conditions. It is concluded that the electrocatalytic oxidation method can achieve satisfactory results in the treatment of wastewater containing refractory organic matter.
